Bulb ReplacementThe headlamp is a semi-sealed beam type which uses a replacablehalogen bulb. The bulb can be replaced from the engine compartmentside without removing the headlamp body.I Grasp only the plastic base when handling the bulb. Nevertouch the glass envelope.1. Disconnect the battery cable.2. Disconnect the harness connector from the back side of thebulb.3. Pull off the rubber cap.4. Press end of the retaining pin together to release bulb.5. Remove the headlamp bulb. Do not shake or rotate the bulbwhen removing it.6. Install the new bulb in reverse order of removal.

Did you hear the one about the Terrano with a charging problem?Just fix it by replacing the thermostat!Seriously - check your temperature gauge does it take ages for the needle to barely get off cold? (and is the heater useless?)The needle should get to just below half way in 2 or 3 minutes.If the thermostat is stuck open, then the engine does not get up to temperature.The glow plug control senses the engine temperature is cold, so the glow plugs stay on for an extended period of time (sometimes 10 to 15 minutes) - short trips particularly in winter, with more headlight driving - the alternator can't keep up with the current being drawn off and from time to time you will end up with a flat battery!A thermostat is cheap, and easy to replace (three bolts and about a half litre of coolant - I pumped the coolant from the top of the radiator, and didn't spill a drop when the thermostat housing was removed).Sure enough, as the engine temperature reached about 50C, the glow plugs turned off.

Hello,
When the MAF on most vehicles reach a point of preventing the engine from starting, you can usually just unplug it and the engine will start. If that doesn't work-
You may want to try having the O2 sensor, ( Oxygen sensor ), checked. It works with other components of the emission system and can cause similar symptoms as the MAF, including preventing the engine from starting.

Did this start happening, after tyres were rotated, or a new tyre was fitted? This will probably reset when the ignition is turned off and back on again, then start flashing after another 80km. This can be caused by the rolling diameter of the wheels being different, and the computer is picking up that a tyre is flat, or that the tyres are of different size designation or different levels of wear. This happened to me after rotating tyres, and would repeat every 40-50km, and went away, when i put the spare, back to being the spare.

The MAF is the most important sensor in your engine, as it tells the computer what it needs to be able to set the mixture on the fly properly at any throttle position. A MAF depends on several other sensors to function. Get your engine codes run and replace any part that is marginal or bad. Good luck.
